Liar: Theresa May told Tory-supporting 17-year-old Calum that taxpayers would support students who would become better-paid, under Labour’s plan to axe tuition fees. But everybody benefits from having well-educated professionals, and there would have been no increase in taxes for the low-paid.

Peter Stefanovic makes a good point (in fact, he’s probably re-stating it, as the Tory penchant for lying to us is well-documented).

The answer to the question in the headline is obvious, though – there isn’t a statutory penalty for politicians lying to the pubic because politicians would have to impose it, and they all know they’re going to want to lie to us at one time or another (with the possible exception of Jeremy Corbyn).

So they lie, and lie, and lie again, and hope that we won’t remember by the time the next election comes around.

That’s why it is our responsibility – those of us who operate within the social media – to record these instances, follow their consequences, and remind the wider world at the necessary time.

When a Prime Minister finds it necessary to lie to a 17 year old on national radio you know the country's hit a tipping point! pic.twitter.com/PEPCuWHjlK
